What is Quantum Yield ?

Quantum yield (Φ) is defined as the ratio of the number of photons emitted to the number of photons absorbed. Notably, quantum yield is independent of instrument settings and describes how efficiently a fluorophore converts the excitation light into fluorescence.

What is the difference between internal conversion and intersystem crossing?

Internal conversions are nonadiabatic processes driven by the kinetic coupling between electronic states, whereas intersystem crossings are mediated by the spin–orbit coupling. The key difference between vibrational relaxation and internal conversion is that vibrational relaxation is the relaxation of an electron that occurs in an electronic state and moves from a high to low vibrational energy level, whereas internal conversion is the movement or relaxation of an electron from a higher to lower electronic state via emission of heat.
